bill murray FDRIt's been a long while since Bill Murray has taken on a serious role. Even in his more dramatic recent fare like 'The Limits of Control' or 'Passion Play,' his characters have offered a slice of charismatic levity in an otherwise more serious environment.

But now, as 'Ghostbusters' fans eagerly await his thoughts on the planned third installment, Murray is turning his attention to something a lot more meaty: President Franklin Delano Roosevelt in the upcoming film 'Hyde Park on the Hudson.'

According to Vulture sources, Murray has signed on to play FDR in Richard Nelson's adaptation of the British radio play, to be directed by Roger Michell ('Morning Glory').
